IMPROVEMENT IN HYDRANTS.

Specification forming part of Letters Patent No. 181,378, dated August 22, 1876; application led g May 8, 1876.

.To all lwhom it may concern:

Be it known that I, LAFAYETTE L. TREMAN, of Ithaca, Tompkins county, New York, have invented an Improved Hydrant or Fire-Plug,

of which the following is a specification, reference being had to theaccompanying draw- Several objects are accomplished by my invention first, the so making the internal tube that it shall contain all the working parts of the hydrant, and be removed, repaired, and replaced without disturbingany part of the outer or ground case; second, the fastening by bolts of the outer case to the branch of the street-main, so that they shall be in fact one, and not easily displaced; third, that the bolts that fasten the ilange of the inner tube to the outer .tube shall be at' or near the surface of the ground, and that they shall tighten the packing between the elbow and inner tube by the draft through the outer case or tube; fourth, to the valvular draining of the water from the inner tube; fth, the rod-recess in Athe inner tube, and to other like objects, as

will be explained.

showing most of the parts in section. Fig. 2 is a horizontal partially sectional view at the base of the inner tube, as by the arrow A. Fig. 3 is a section at the flange of the inner tube, as seen by arrow B; and Fig. 4 is a section of the square part of the valve-rod, showing the side bearings that prevent its revolving, as indicated by arrow O. 4

In Fig. 1, a is the elbow or source whence the water comes, which is bolted to the outer case b, as seen. A It may be cast as part of the outer case b. The outer case reaches to d, which is a flange fast to it at or near the surface of the ground. Here is a bolt-ing together of two parts--namely, the outer case b by its ange d, and the inner tube by its ange c; and, if thought best, the same bolts o may hold a flange tothe Atop case or ire-pl'ugj', which projects above the'ground to the cap f. On the top of this cap is the burr or nut g ofthe hollow nut g, which extends down to and receives the screw h of the valve-rod z'. This rod is square at i', where it slides in the side guides or clamps j, which prevent the valveder, and the valve-rod is smaller below, as it slides in the opening in the septum e of that part of the inner tube e and continues on to the valve j', which is yfast on its lower end.y

This smaller part of the rod and shoulder actsI as a valvular opening to drain the water out of the pipe ewhen the valve is closed. When the valve is open, the shoulder il comes down ou the septum e', and prevents the flow of water about the rod. The drainage escapes at fm at the left through the outer case b. The valve-rod lies in a recess, fr', made in the inner tube for this purpose, which is better seen by the vertical Figs. 3 and 4. When-the valve j' is opened, the water rises in the inner tube in the space, whose shapeis better seen in Figs. 3 and 4.. The nut g is held by the clasp n on the top of the inner tube. At m is seen a flange or bearing cast as part of the elbow a, with a gasket or packing, m, which is held on the base e of the inner tube by the projection e'", made for the pur/pose, and which is or may be made beveling, the better to hold the gasket or packing on it. A Another packing, a', is seen between the outer case and the elbow.

The same letters indicate the same parts in the other figures.

It will be noticed that, the .nut s being removed from the top of the cap f of the hydrant, and the bolts c', if used, through a ange on the plug or upper part of the hydrant-case f, the plug-case f is easily taken oli', leaving the inner tube and the outer case b undisturbed. The bolts o being taken out has relieved the strain or pressure made through the wallsl of the case b and tube e on the gasket m". .And it is clear that the. inner tube, with all the working parts of the hydrant, which are attached to this inner tube, cannow be taken out, leaving the case b and its prolongation a, or elbow, undisturbed in the ground., It is now examined, repaired, a new inner tube put in its place, or anything else is done that is desired; and it is readily readjusted by being slid in the case b, the gasket mf going to its place, and the bolts c tightened, which closes the gasket on the seat a of the joint at the base of the hydrant.
